Koyo Solid State Multi Band Portable Radio Appraisal

Koyo Solid State Multi-Band Portable Radio

This is a vintage Koyo solid-state multi-band portable radio, likely dating from the 1960s to 1970s given its design and 'solid state' labeling, which was a significant selling point at the time. The radio features a rectangular form factor with visible dimensions suggesting it is a medium-sized portable unit, possibly around 10-12 inches in height and 6-8 inches in width. The casing appears to be constructed from a combination of materials. The main body is encased in a faux wood-grain material, likely a veneer or laminate over a core of wood or particle board, providing a classic, warm aesthetic. The front panel is predominantly black, with a large speaker grille area on the left side, covered by what seems to be a solid black material, perhaps perforated metal or fabric, though it's not clearly visible. The right side of the front panel houses the tuning dial, which is a key visual element. This dial displays multiple frequency bands including AM, FM, LW (Long Wave), SW (Short Wave), and what appears to be a 'Police' band, indicating its multi-band functionality. The frequencies are marked with various colored lines and numbers, suggesting a detailed and potentially complex tuning mechanism. A vertical silver-colored strip separates the speaker area from the tuning dial, and it appears to have band selection buttons or switches. Below the main display, there's a horizontal silver-colored control panel. This panel features at least three rotary knobs with textured surfaces for grip. One of the knobs is labeled 'Bband' (possibly 'Band'), suggesting it's for band selection; another is likely for volume, and potentially a third for tone control or fine-tuning. There's also a smaller circular opening on the far left of this control strip, which might be a headphone jack or an input. The overall condition shows signs of age and use, with some visible wear on the faux wood casing, potentially some scratches or scuffs on the black and silver front panels. The silver trim, particularly around the edges of the front panel, shows some tarnishing or minor discoloration consistent with its age. Despite the wear, the primary controls and display elements appear largely intact and legible, suggesting it has been reasonably well-preserved for a vintage electronic item. The 'Koyo' logo is prominently displayed on the upper left of the speaker grille area, next to a stylized 'H' and 'M' mark, serving as a clear manufacturer's identification. The 'SOLID STATE MULTI BAND' text on the tuning dial further highlights its advanced technology for its era. The craftsmanship appears competent for a consumer electronic device of its time, balancing functionality with a sturdy, appealing design.
